Answer:
84
Step-by-step explanation:
The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid
The area of a trapezoid is given as:
1/2(b1 + b) × h
Where:
b1 = Base 1 = 10
b2= Base 2 = 18
h = Height = 6
Therefore, the area of a trapezoid =
1/2 (10 + 18) × 6
= 28/2 × 6
= 84
Therefore, the area of the trapezoid = 84
Answer: x = 3
Step-by-step explanation: 10 x + 20 = 5x + 35
10 x + 20 - 5x = 35
5x = 35 - 20
5x = 15
x = 3
Y + 7 = y - 3
y - y = -3 - 7
0 = -10 (incorrect)...so this problem has no solutions
Answer:
y=10 x=30
Step-by-step explanation:
3x=90
x=30
2(30)+3y=90
60+3y=90
3y=30
y=10
